Rexroth A7V Series High-Pressure Bent Axis Variable Pump/Motors

Product Overview: The Rexroth A7V Series is a classic bent-axis axial piston variable unit, widely utilized as either a pump or motor in various open-circuit hydraulic systems. Renowned for its robust mechanical design and extreme power density, the A7V series is a staple in heavy-duty engineering. This selection features core configurations for A7V160 (160cc) and A7V20 (20cc), covering LV (Constant Power), EP (Electric Proportional), DR (Pressure Control), and EL (Electric Control). Whether in large industrial presses, metallurgical equipment, or mobile machinery, the A7V series delivers precise flow and torque output at peak pressures up to 400 Bar.

Key Technical Advantages:

• Versatile Control Synergy:

  • LV1 (Power Control): Automatically adjusts displacement based on load pressure to maintain constant power output and prevent prime mover overload.

  • EP1 (Electric Proportional): Stepless displacement regulation via electric signals, ideal for highly automated modern hydraulic systems.

  • DR (Pressure Control): Automatically reduces displacement upon reaching the set pressure for energy savings and system protection.

  • EL (Electric Control): Utilizes electric feedback for staged or continuous control, enhancing response accuracy.

• High-Pressure Robustness: Rated for 350 Bar (5100 PSI) continuous and 400 Bar (5800 PSI) peak pressure. Built with reinforced rotating groups for extended service life.

• Bent Axis Technology: Compared to swashplate designs, the bent-axis architecture offers superior self-priming capabilities and higher mechanical efficiency at high rotational speeds.

• Target Applications: Industrial hydraulic power units, forging machines, marine deck machinery, excavator power units, and heavy-duty conveyor systems.
